Abstract (en)
In a rubber blend consisting of: a polybutadiene blend (A)+(B) composed of: (A) not less than 30% by weight but less than 70% by weight of a high molecular weight polybutadiene comprising as the main component a polybutadiene having an intrinsic viscosity Ä eta Ü of 3.0 to 7.0 as measured in toluene at 30 DEG C and a cis-1,4-configuration content of at least 80% and (B) more than 30% by weight but not more than 70% by weight of a low molecular weight polybutadiene comprising, as the main component, a polybutadiene having an intrinsic viscosity Ä eta Ü of 0.1 to 0.5 as measured in toluene at 30 DEG C, and (C) a diene type rubber other than the above components (A) and (B), the rubber blend (A)+(B) is contained in a proportion of 35 to 95 percent by total weight of rubber blend (A)+(B)+(C), thereby providing a rubber blend suitable for a tire; said blend being greatly improved in wet skid performance and ice skid performance with retention of the abrasion resistance of a conventional polybutadiene.
